Pedro Garcia, don't know where you live in MI, but up here in northern MI, there are plenty of old Primestar dishes and BUDs people will give you for the asking just to get rid of them.
Oops! Posted that before I saw you live around the Kazoo area. Just take a drive in lthe country, there will be plenty of dishes available. I have 2 BUDs and 5 KUs, the most I ever paid was $20 for an exceptionally nice 8' mesh BUD. The P* dishes are exceptional in their durability.
